So I was one of the folks today that had steam crash at launch after taking the July 31st Beta Client update…
(steam:3753808): Gtk-ERROR **: 16:33:40.346: GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported
/home/<userid>/.local/share/Steam/steam.sh: line 928: 3753808 Trace/breakpoint trap (core dumped) "$STEAMROOT/$STEAMEXEPATH" "$@"
Thankfully steam re-released within an hour of my (and I’m assuming others) bug reports… adding the following detail to the release notes:
Note: This beta was re-released to fix a crash on Linux if 32-bit GTK-3 libraries are installed.
So this got me thinking… why do I have 32-bit gtk3 libraries installed on my system and do I need it?
Assuming lib32-gtk3 is the “offending” package, I checked to see what depended on it:
pacman -Qi lib32-gtk3
And got a list of details with an empty “Required By” section.
Details
$ pacman -Qi lib32-gtk3

Thinking that maybe something changed over time with the dependencies I also ran…
pacsift --cache --any --depends="lib32-gtk3" --optdepends="lib32-gtk3" 2>/dev/null
which also returned nothing…
So just in case I’m missing something… can anyone think of a reason to not remove lib32-gtk3 off a KDE Plasma based install?
